AUTOMATIC RAZOR.

I Specification of Letters Patent.

Patented Sept. 29, 1908.

Application filed March 5, 1906. Serial N... 304,244.

To all whom it may concern: I

Be it known that I, J OHN K. J own, a citi- Chicago, Cook county,Illinois, have invented a certain new, useful, and Improved AutomaticRazor, of which the following is a full, clear, and exact description,such as will enable others skilledin the art to which it appertains tomake and use the same.

My invention relates to improvements in razors and has particularreference/to improvements in razors of that class known as safetyrazors.

The object of my invention is to provide a razor which may be usedwithout special skill on the part of the person who is shaving himself,in other words, a razor of the safety type.

A further and particular object of my invention is to provide a razorwhich shall be automatic in action, that is to say, a device in whichthe cutting blade shall be moved with great rapidity; so that to do itsproper work the device need only be held against the face and movedslowly thereon, the user being relieved from the necessity of exercisingspecial care or skill in the manipulation of the razor.

My invention consists generally in an automatic razor which comprises aknife guard, having a suitable handle, in combination with a knife orblade arranged for reciprocation in said guard and means for rapidlyreciprocating said knife.

Further, my invention consists in an automatic razor comprising a knifeguard having a handle, in combination with a razor blade arranged formovement in said guard and a suitable motor provided in said handle andconnected with said blade, for operating the blade in the guard.

Further, my invention consists in the combination of a razor blade witha casing or guard therefor and an mechanism for actuating said blade.

The invention also consists in various details of construction and incombinations of parts, all as hereinafter described and particularlypointed out in the claims.

The invention will be more-readily understood by reference to theaccompanying drawings forming a part of this specification, and in whicFigure 1, is alongitudinal section of an automatic razor embodying myinvention. Fig. 2, is a transverse section thereof on the irregular lineX X knife or blade is electro magnetic of Fig. 1. Fig. 3, is a sectionaldetail 'on the line YY of Fi 2. Fig. 4, is a diagrammatic view of theelectric circuit of the device. Fig. 5, is a view similar to Fig. l, butshowing an electro magnetic mechanism of modified form. Fig. 6, is across section on the line ZZ of Fig. Fig. 7, is a diagram of theelectric circuit of the electro magnetic motor of Fig. 5.

In carrying my invention into effect, I prefer to employ a handle, A,which carries the razor guard or the motor, C. The remaining principalele ment is the razor knife or blade, D, arranged Within the guard, B,and operated by the motor, C. The guard, B, preferably comprises theannular ring, 2, the plate, 3, and the light, hinged part or hood, I.The edge of the plate, 3, is provided with guard teeth or fingers, 3,which constitute the guard proper and a slot is left between the parts 3and 4, through which the sharp edge of the knife extends and operates.The knife, I), is held on a knife carrier, 5; the knife, I), havingopenings, 1), near its edge and the carrier having lugs or hooks, 5',which ongage the knife as shown in Fig. 1. The preferably slightlyinclined with respect to treme edge may lie close to the surface, 3", ofthe guard. The motor hereinafter described is arranged to reciprocatethe blade and as it is desirable that the blade shall perform adrawingcut or compound movement, I provide the carrier with relativelyinclined or ,angular guide members, 6, 6. These are preferably Z shapedin section (see Fig. 3) and they en age with guide lugs, 7, struck andformed from the plate, 3. Thus the knife is made to move angularly withrespect to the guard. fObviously other means may be devised for holdingthe carrier in such man ner that the knife will be reciprocatcd bothlongitudinally and transversely when the carrier is subjected to avibratory force; and in this regard, as in others hereinafter specified,my invention is to be construed as including equivalent structures, and.not confined to the specific devices or constructions herein shown anddescribed. To prevent: movement of the knife on the carrier, 5, thatcasing, B, and contains is to lock the knife on the carrier, I prefer touse. a small spring, 5", formed from the metal composing the carrier,'5, and engaging the rear edge of the knife, also slightly over lappingthe outer surface thereof, as shown in Fig. 1.

, ing the razor blade or solenoid, 10, and a core, 11, but it should beThis deviceholds the knife on the lugs 5 knife may be released from thecarrier by forcing the spring, 5", backward and downward.

The handle, A, is screwed into the ring, 2,

which has a recess to receive 1t; but first I.

place a rubber diaphragm, 8, and a dished stop-plate, 9, in the recess.When the handle is screwed home the diaphragm, 8, is bound between thering and the plate, 9. The razorproper becomes wet when used and thepurpose of the diaphragm is to exclude moisture from the tubular handle,A. The opposite end of the handle is closed by a cap or plug, A.

In constructing my novel device, I prefer to use an electro-magneticmotor for actuatknife. I have herein shown a reciprocatingelectro-magnetic motor for this purpose, the same comprising aunderstood that my invention is not limited or confined as to aspecialform of motor, it being obvious that an electro-magnetic motor ofanother form or type or a rotary elec-. tric motor, or a purelymechanical motor may be substituted for the mechanism shown.

The coil of the solenoidal motor shown in Fig. 1, is an ordinary coil orhelix having latter having an opening to ring, 13, and

suitable ends, 10, of insulating material. It is inclosed in aninsulating jacket, 12. The handle is provided with an internal annularrib, A", and the solenoid is held between this and the plug, A.

10", represents a light, metal ring on the part, 10', and connected withone end of the coil. The opposite end of the coil is connected to alight spring, 10", on the other insulating part, 10. This last engagesan insulated ring, 13, on the inner side of the plug, A. I

14 and 15,-represent spring contacts on the the insulated bushing, 16;the receive one of the terminals of a battery circuit. The otherterminal, 17, enters a hole .or' socket in the metal plug, A.

The circuit closer, 10, arranged on the handle is adapted to be pressedagainst the metal part, 10", and is used to complete the circuit throughthe coil and battery. The contacts, 14: and*15, and the extension, 11,on the core, 11, form an interrupten. Said extension is adapted toengage the part, 14, and force it away from the contact, 15, therebyopening the circuit after the coil has been energized to draw in thecore. The core is equi 'ped with an adjustable stop, 11*, and a fixestop, 11 for limiting its movement or stroke. The sprin 18, serves toreturn the core when the coil is deenergized by the breaking of theconnectionfat'contacts, 14 and. 15. It is obvious that the core will beand fiat upon the carrier. The

rapidly reciprocated wheneverthe circuit is closed at 10.

The end of the core, elastic diaphragm, 8, and is connected with theknife carrier by any suitable mechanism, such as the toggle device, E,which forms a part of the motor. This portion of the mechanism comprisesthe link, 19, and the links, 20 and 21. For convenience I preferablymake the end of the core of two thread ed parts, which incidentally,serve to bind the inner edges-of the diaphragm, 8, upon the core asshown in Fig. 1. The part, 11, carries the pivot for the link, 19, theend of which is of reduced thickness. I prefer to make said link, 19, ofsheet metal and substantially V shaped to increase its speed or width atthe outer end. It has several pivot openings, 19, which provide fortheadjustment of the stroke of the knife carrier, the Wire link, 21,having ends which may be snapped into either pair of holes, 19. Thelink, 20, has its bent ends or pivot portions held in lugs, 20, whichare struck up from the plate, 3.- Similar lugs, 21", on the carrier, 5,receive the cross portion of the link, 21.

In Fig. 1, the parts are shown in dcencrgized position, at such time therazor isin retracted position. When the solenoid is energized the corebeing drawn back strengthens the toggle and thereby projects the razoracross tie safety guard. This movement is accomplished many times in aminute, through the automatic operation. of the motor. As before statedthe movement of the core and the stroke of the to gle mechanism may bevaried at will to regu ate the operation of the razor, as may bedesired. By slight modifications of the parts I may do away with theknife carrier and connect the motor directly to the razor blade. Thedevice shown in Fig. 5, differs from that hereinbefore described only inthe form of its motor. In this case I use double or opposed solenoids.My object in so doing is to dispense with The solenoids used are likeunto the solenoids 10, of Fig. 1, but are shorter. They are arranged inan insulating casing after the manner of Fig. 1, and their cores areconnected by non-magnetic bar, 22. The solenoids are alternatelyenergized and reciprocate the compound core. 4 ring, 10", is preservedon the end of the solenoid 1, to cooperate with the circuit closer, 10.The coils are wound in opposite directions, as indicated in thediagrammatic view of Fig. 7 and the automatlc connection of the coilswith the battery is brought about by. means of the make and break deviceat the end of the core. comprises the disk 23, mounted on the core,insulated therefrom and cooperating with the terminal spr or contacts 24and 25,

the retracting spring, 18.

The contact This device 11, passes through the soa's'ro gram. The disk,23, has an electrical connection'with one branch of the battery circuit,while the metal handle is connected with the other branch of saidcircuit.

- Therefore, when the circuit is closed at 10,

one of the coils will be energized to indraw the core. This movementwill be followed by the breaking of the circuit between thecorresponding contact and "the disk, 23, and the completion of thecircuit of the other coil through the other contact ,the energizae tionof the second coil causing an opposite movement of the core. In thismanner the.

coil is kept in rapid movement as long as the circuit is closed betweenthe parts l0 and 10". 26;"repfe'sents a stop forlimiting the stroke ofthe core, same being arranged on the connecting bar, 22. g

The use and operation of my automatic razor is extremely simple. "Whenthe face.- has been lathered and is in readiness for,

the razor, the user simply grasps thehandle and places the razor guardagainst his face. He then depresses the circuit closer, 10 whereupon therazor blade is set into rapid movement and, the device being slowly.

passed over the face, rapidly and comfortably performs the shavingoperation;

As numerous modifications of the structure herein shown and describedwill readily suggest themselves to one skilledin the art, I do notconfine my inventionthereto.

Having thus described my invention I claim as newand desire to secure byLtters Patent:
